I can’t be sure yet, but it seems to have something to do with the Autopilot Plus flight and the new preflight.
Yesterday, on my way to Singapore, I connected in the middle and accelerated after receiving a 90knots wind, and then connected again with Autopilot Plus. After that, I had a flight in New York, but I had an error that the ground wind was set to 90 knots alone. Accordingly, unlike other players, I was able to take off and land vertically with the A220. (The reason for this basis is that ATIS’s METAR was actually about 9 knots before I connected, but as soon as I connected, it became 90 knots and it was normalized about 10 minutes later.
However, it was confirmed that the wind was blowing normally when spawning at another airport, and the problem only occurred at JFK in New York, the first spawning place.
Additional suspicions do not seem to apply to other users. ATIS changed to 90 knots wind 3 minutes after I connected, and I was affected by it, but the A350 that just took off started without any impact, and the 90 knot wind was only affected by me.
Believe it, the last picture is almost a vertical takeoff from runway 22. To summarize, there is a bug that synchronizes the speed of the air wind with the newly started flight.
